I'm arguing against the many comments in this thread that called the police a "worthless institution" because of some anecdotes, which is analogous to saying "sql is slow" because you particular query is slow; instead both subjects require thought about realistic scenarios and expectations to understand why things are the way they are.

They're interested but they're not there to appease. As I already said several times before, police need laws and courts to back them up or their work is ineffective. You should contact your maylor and local DA about why that jurisdiction has so many face punchings by the homeless in the first place.
